Photovoltaic Cell: Photovoltaic cells consist of two or more layers of semiconductors with one layer containing positive charge and the other negative charge lined adjacent to each other. Sunlight, consisting of small packets of energy termed as photons, strikes the cell, where it is either reflected, transmitted or absorbed.
Photovoltaic (PV) Cell Structure. Although there are other types of solar cells and continuing research promises new developments in the future, the crystalline silicon PV cell is by far the most widely used. A silicon photovoltaic (PV) cell converts the energy of sunlight directly into electricity—a process called the photovoltaic effect—by using a thin layer or wafer of silicon
PV cells can be categorized according to application, cell material, and structure, and cost within the system application context. The three application areas are terrestrial solar, space solar, and nonsolar. For example, thermophotovoltaics (TPV) systems use man-made infrared energy sources at night.

As researchers keep developing photovoltaic cells, the world will have newer and better solar cells. Most solar cells can be divided into three different types: crystalline silicon solar cells, thin-film solar cells, and third-generation solar cells.
... solar cells are classified on the constituent for the production of the solar cell. The classification is as follows; Crys- talline Silicon, Thin film, Organic/polymer, Hybrid PV and...
The color of this type of solar cell is dark blue which lets us detect if a panel belongs to this type of cell. Those solar panels with dark blue cells are polycrystalline solar panels. Another difference between both types
The three main types of photovoltaic (PV) cell include two types of crystalline semiconductors (Monocrystalline, Polycrystalline) and amorphous silicon thin film. These three types account for the most market share.
We can separately examine solar cells as three broad classes: (1) nonorganic- or inorganic-based solar cells; (2) organic-based solar cells; (3) hybrid solar cells, which are made by the mixture of organic and inorganic materials. Though inorganic and hybrid solar cells are out of the scope for this part, brief information will be given.
A schematic diagram of a photovoltaic cell (PV cell) or solar cell is given in the figure. It relies on light, which affects the junction between two types of semiconductors called p-type and n-type. The N-type has excess electrons and the p-type has a shortage of electrons.

Much research is focused on increasing the efficiency and decreasing the cost of these cells by investigating alternatives to the anode, dyes, cathode, and electrolytes of dye cells. Organic Photovoltaic (PV) Cell. Another type of thin-film cell is the organic photovoltaic cell (OPV). In its basic form, the OPV consists of a single layer of
Photovoltaic cells are semiconductor devices that can generate electrical energy based on energy of light that they absorb.They are also often called solar cells because their primary use is to generate electricity specifically from sunlight, but there are few applications where other light is used; for example, for power over fiber one usually uses laser light.
There are three types of PV cell technologies that dominate the world market: monocrystalline silicon, polycrystalline silicon, and thin film. Higher efficiency PV technologies, including gallium arsenide and multi-junction cells, are less
